The horizontal line has equation y=3. The line is solid, and everything below it is shaded, which translates to the inequality y\le3. (so not B nor D)

The dashed line must have equation y=2x-1. Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both x=0 and y=0, so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be y>2x-1.

This means the answer is A.

Given f(x)= 3x-1 and g(x)= 2x-3, for what value of x does g(x) =f (2)?
Tasya [4]

Answer:

At x = 4 ⇒ g(x) = f(2)

Step-by-step explanation:

* In the functions f(x) = 3x - 1 and g(x) = 2x - 3, the domain is

  the values of  x and the range is the values of y

∵ g(x) = f(2)

* Then you will use the range of f(x) at x = 2 to find the domain of g(x)

∵ The domain of f(x) = 2

∵ f(x) = 3x - 1

∴ f(2) = 3(2) - 1 = 6 - 1 = 5

* The range of f(x) = 5

∵ f(2) = g(x)

∴ 5 = g(x)

∵ g(x) = 2x - 3

∴ 2x - 3 = 5 ⇒ add 3 to both sides

∴ 2x = 8 ⇒ divide both sides by 2

∴ x = 4

* At x = 4 ⇒ g(x) = f(2)

Jess had three more nickels than dimes for a total of $1.50 how many of each coin did he have
lara31 [8.8K]
N=d+3 because she has 3 more n than d

5n+10d=150

These are givin 5cents in a Nickel so it’s 5n
10 cents in a dime so it’s 10d
We need her to have 150

Now substitute what we know n to be
Into the equation and solve

5(d+3) + 10d = 150
5d + 15 + 10d = 150
15d + 15= 150
15d=135
D=9

Jess had 9 dimes and 12 nickels
